The memory 140 may be a subordinate element of the processor 170.

Under the control of the processor 170, the light generation unit 160 may convert electrical energy into light energy.

The light generation unit 160 may include an array module 200 on which a plurality of micro Light Emitting Diode (LED) elements is disposed.

A micro LED element is an LED chip of a few micro-meter. For example, the size of a micro LED element may be 5 to 15 um.

The array module 200 may include a substrate and a subarray in which the plurality of micro LED elements is disposed. The array module 200 may include one or more subarrays.

The subarray may be in any of various shapes.

For example, the subarray may be in a shape of a figure-having a predetermined area.

For example, the subarray may have a circular shape, a polygonal shape, a fan shape, or the like.

It is desirable that the substrate includes a Flexible Copper Clad Laminated (FCCL) substrate.

The array module 200 in which the plurality of micro LED elements is disposed will be described in more detail with reference to FIG. 6 and its following drawings.

The light generation unit 160 may form a first light distribution pattern with light that is generated by the plurality of micro LED elements.

The first light distribution pattern may be defined as a pattern that is formed on a vertical plane, such as a screen, that is located at a particular distance when light generated by the light generation unit 160 is emitted to the vertical plane.

For example, the vertical plane may be defined as a virtual screen in the sense that the vertical plane represents a plane on which light would project based on an actual screen being placed at the location of the vertical plane.

The vertical plane may be referred to as a light distribution screen.

The vertical plane may be located at a first distance from the light generation unit 160. The first distance may be, for example, a distance that facilitates measurement of the light distribution pattern of a vehicle lamp. In some scenarios, the distance may be specified by vehicular regulations that specify a light output quantity and/or light output pattern of a vehicular lamp at a particular distance.

For example, the vertical plane may be located at a first distance that is from 20 m to 30 m from the light generation unit. In some implementations, the first distance is desirably 25 m.

In some scenarios, when a vertical plane (e.g., a screen) is at a distance of 20 m to 30 m from a light source, this may facilitate seeing a light distribution pattern of a head lamp projected on the vertical plane.

By contrast, in some scenarios, within a distance less than 20 m from a light source, it may be more difficult to secure a sufficient light distribution area. And in some scenarios, when light is distributed at a distance greater than 30 m from a light source, it is difficult to measure luminous intensity of the light.

The examples that follow will describe light distribution patterns that are based on a projection onto a vertical plane (e.g., a screen) that is located at a first distance from the light generation unit.

In some implementations, the light generation unit 160 may be configured to form a first light distribution pattern on a vertical plane at the first distance from the light generation unit 160 such that a plurality of zones of the first light distribution pattern respectively has different luminous intensities.

A central point of the first light distribution pattern may be defined on the vertical plane at the first distance from the light generation unit 160.

The central point may be defined as the center of the first light distribution pattern, and may be a point on the vertical plane at which light generated by the light generation unit 160 has the highest luminous intensity.

Alternatively, the central point may be defined as the point corresponding to the shortest distance from the light generation unit 160 to the vertical plane.

The first light distribution pattern may be formed in a range of 62 to 8,000 candela(cd).

In some scenarios, if the luminous intensity projected by the lamp at a specific point on the vertical plane at the first distance is smaller than 62 cd, then this may result in difficulty to secure a sufficient forward field of vision for the driver in foggy weather.

Conversely, if the luminous intensity projected by the lamp at a specific point on the vertical plane is greater than 75,000 cd, then this may result in disturbing other drivers located nearby the vehicle.

In some implementations, the light generation unit 160 may be adjustable. For example, the position adjustment unit 165 may adjust a position of the light generation unit 160.

The position adjustment unit 165 may control the light generation unit 160 to be panned. Due to the panning control of the light generation unit 160, output light may be adjusted in a left-right direction (e.g., the overall width direction).

The position adjustment unit 165 may further include a driving force generation unit (e.g., a motor, an actuator, and a solenoid) that provides a driving force required to adjust a position of the light generation unit 160.

When the light generation unit 160 generates a low beam, the position adjustment unit 165 may adjust a position of the light generation unit 160 so as to output light further downward as compared to the case where the light generation unit 160 generates a high beam.

When the light generation unit 160 generates a high beam, the position adjustment unit 165 may adjust a position of the light generation unit 160 so as to output light more upward than the case where the light generation unit 160 generates a low beam.

The processor 170 may be electrically connected to each unit of the lamp 100. The processor 170 may control overall operation of each unit of the lamp 100.

The processor 170 may control the light generation unit 160.

The processor 170 may control the light generation unit 160 so as to form a first light distribution pattern.

By adjusting an amount of electrical energy to be supplied to the light generation unit 160, the processor 170 may control the light generation unit 160.

The processor 170 may supply a different amount of electrical energy to each region of the array module 200.

For example, the processor 170 may supply electrical energy whose amount is gradually smaller from the center to the periphery of the array module 200.

The processor 170 may receive driving situation information through the interface unit 130.

The processor 170 may receive object information through the interface unit 130.

The object information may be external light information.

For example, the processor 170 may acquire external light information that is acquired by processing an image captured by a camera.

The processor 170 may acquire external light information based on data generated by the sensing unit 120.

The processor 170 may control the light generation unit 160 based on the external light information so as to form a first light distribution pattern.

The processor 170 may control the light generation unit 160 so that light generated by the light generation unit 160 is combined with external light to form the first light distribution pattern.

The processor 170 may acquire external light information of each region external to the vehicle 10.

The processor 170 may determine an amount of light required to be output to each external region of the vehicle 10 so as to form the first light distribution pattern.

The processor 170 may control the light generation unit 160 to output a different amount of light to each external region of the vehicle 10 so as to form the first light distribution pattern.

For example, based on the above determination, the processor 170 may adjust an amount of electrical energy to be supplied to a plurality of micro LED elements (e.g., a first subarray) emitting light to a first region external to the vehicle 10, and may adjust an amount of electrical energy to a plurality of micro LED elements (e.g., a second subarray) emitting light to a second region external to the vehicle 10.

In some implementations, external light may be light generated by a streetlight or a lamp of a nearby vehicle.

The processor 170 may adjust the first light distribution pattern based on driving situation information.

For example, the processor 170 may adjust the first light distribution pattern based on navigation information.

For example, the processor 170 may adjust the first light distribution pattern based on information regarding a roadway in which the vehicle 100 is travelling.

For example, when the vehicle 100 is travelling in a highway, the processor 170 may adjust the first light distribution pattern so that light is output with a narrower width and a longer length.

As another example, when the vehicle 100 is travelling in an urban setting, such as in a city downtown, the processor 170 may adjust the first light distribution pattern so that light is output with a wider width and a shorter length.

For example, the processor 170 may adjust the first light distribution pattern based on object information.

For example, when the vehicle 10 receives information regarding a nearby vehicle travelling in a lane next to a lane in which the vehicle 100 is now travelling, the processor 170 may control the light generation unit 160 to output light in the lane in which the vehicle 10 is travelling.

Under the control of the processor 170, the power supply unit 190 may supply electrical energy to each unit of the lamp 100. In particular, the power supply unit 190 may be supplied with power from a battery inside the vehicle 10.

The vertical centerline 511 may be defined as a line that extends from the central point 500 in an upward-downward direction to be perpendicular to a horizontal centerline 512.

The screen 300 may be divided into an upper part and a lower part by a centerline 512 (hereinafter referred to as a horizontal centerline) which extends in a left-right direction.

The horizontal centerline 512 may be defined as a line that extends from the central point 500 in a left-right direction to be perpendicular to the vertical centerline 511.

A point at which the vertical centerline 511 and the horizontal centerline 512 intersect with each other is the central point 500.

For example, luminous intensity in the entire region of the first zone 510 may be 62 to 8,000 cd.

The second zone 520 is a region in the shape of a second rectangle from which the first rectangle 510 has been removed.

The second rectangle has a pair of points 521 and 522 as lower vertices which are positioned on the horizontal centerline 512, and which forms an angle of 26 degrees relative to the virtual reference line 301 in the horizontal direction 321 and 322 with respect to the light generation unit 160.

A point 523 at an angle of 3.5 degrees relative to the virtual reference line 301 in the upward direction 332 is positioned on an upper edge 524 of the second rectangle.

The first light distribution pattern may be formed such that the second zone 520 has luminous intensity from 0 to 400 cd.

For example, luminous intensity in the entire region of the second zone 520 may be 0 to 400 cd.

A third zone 530 is a region in the shape of a third rectangle.

The third rectangle of the third zone 530 has a pair of points 531 and 532 as lower vertices which forms an angle of 26 degrees relative to the virtual reference line 301 in the horizontal direction 312 and 322 with respect to the light generation unit 160, and which forms an angle of 3.5 degrees relative to the virtual reference line 301 in the upward direction 332 with respect to the light generation unit 160.
